Application lod VOctober 22, 1.906!l Serial No. 840,077 i To all whom itmayvconcem: Be it known that I, TERRY Bmx'r, a citizen of the UnitedStates, residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, 4have invented I bination and arrangement 0f parts, `aswill behereinafter described and claimed,

` One obj ect of my invention is to provide a machine of this characterwhich will bey of simple and durable construction, and by means of whichthe mixing may be effectively and expeditiously performed.

A further object of my invention is to effect improvements in the Ameansfor feeding and discharging the material into and from the mixingreceptacle or container. v

The above and other objects, whiclwill appear as the nature of myinvention is more fully understood, are accomplished by the'constructionillustrated in the accompanying drawings1 in which,-

Figure 1 is-a top plan view-of a mixing machine embodying myimprovements; Fig. 2 is a side elevation of the same;` Fig. 3 is an endelevation; Fig. 4 is a verl tical longitudinal sectional view, taken onthe linel 4-4 of 'F-ig. 1; Fig. 5 is a vertical transverse sectional.view; and Fig.` 6 is a detail vertical transverse sectional view, takenon the line 6 6 ofFig. l and showing the swinging mixer-carrying framein full lines in-its normal position, and in dotted lin`es in its tiltedposition.

Referring to the drawings by numeral, 1 denotes ya frame or support,preferably consisting of two enduprights 2 and 3 connected by alongitudinal bar or beam 4. Each of said uprights is formed withsupporting feet 5 upon which wheels or rollers may be mounted, ifdesired, to permit the frame to be readily triansported.V The connectionbetween the bar 4 and the uprights 2 and 3 is preferably'detachable,and, as shown, consists in forming the ends of the bar 4 with reducedportions 6 which project through openings formed in the, uprights 2 and3 and are retained therein by wedgeshaped keys 8. Said keys paw throughopenings v formed in said reduced ends of the bar4 and are preferfrombeing lost.

Upon theupper ends of. the uprights 2 and 3 are formed semi-circularbearings `10 in which are removoscillating or tilting frame 1 2 whichcarries a mixing 'receptacle or container 13. Said frame 12'ispreferably constructed of two half-sections 14,V 15, which arehereshownin theform of fmetalcastings. Each of said half-sectionscomprises a body portion 16 having at one of its ends one of thetrunnions 11, and at its opposite end a transversely extendingsemi-cylindrical casing section 17 which is formed along its 4side edgesupon the two casing sections 17 are secured together by bolts or othersuitable fastening means 19, said sections 17 forming a substantiallycylindrical shaped casing,its ends,which are open, being somewhattapered,

`as shown. The mixing receptacle or container 13, which is in the formof a hollow cylindrically shaped shell formed with taperedfends 20, 21,-is mounted to rotate within the transversely disposed casing 17, ballbearings 22 being provided between the outer surface of said receptacleand the inner surface ofthe casing 17 `to permit the former to rotatewith a minimum amount of friction. The ball bearings are retained withinthe casing by annular plates 23 and are adapted to be inserted into thesame through the openings 24 formed in said casing and closed by caps25, said openings also serving to permit an oil or lubricant to bedistributed upon the bearing balls 22. The interior of the mixingreceptacle 13 is formed with spiral-ly arranged rows of inwardlyprojecting and angularly disposed wings or blades 26 which serve tothoroughly agitate or mix the material within the receptacle when thelatter is rotated, as will be presently described. The material to bemixed is introduced through the tapered end 20 of said receptacle bymeans of a tapered trough 27 which is preferably mounted upon theadjacent end of th'e .casing 17 by means of braces-28. The opposite end21 of the mixing receptacle the latter.

llt will be seen upon reference toFigs. 1 and6 of the 13 serves as adischarge for drawings, thatthe ,trunnion's' 1 11are disposed eccen-`-being of greater size and "weight than the corresponding portion of theother section 14. Owing to this construction, it will be seen that whensaid frame is hung upon the uprights'2, 3, its overbalanced side orportion 'with angular'ly projecting flanges 18. Said flanges 18 willswing downwardly and, since the discharge end ings, I preferably employalever 30l which is pivo'ted.

intermediate its ends at 3l upon the inner side of the assist insupporting the swinging or tilting frame 12,

the flanges 18 upon'the underside of the casing 17 are curved orarc-shaped, as shown at 37, and are adapted to engage a supportingfriction roller 38 which is journaled in a block or bearing 39 securedcentrally upon the bar 4 of the frame 1.

In order to rotate the mixingreceptacle 13, I preferably journal, in theenlarged or overbalanced portion of the frame l2, a shaft 40 4,which hassecured upon its inner end a pinion 41 disposed in a recessed portion 42of said frame. Said pinion meshes with a toothed gear 43 which issecured upon the outer side 4of the receptacle 13 and rotates in arecessed portion 44 of the casing '17, as shown. which `projects beyondthe upright 3, has secured upon it a fly Wheel 45 which is provid edwith a crank han-y dle 46, by means of which, said wheel, and. hencesaid shaft, may berotated. If desired, the shaft 40 may be driven bypower by placing tight and loose pulleys upon the same, as will bereadily understood. In the frame 12 is provided a covered lubricatingopening 47, through which oil or other lubricants may be supplied to theshalft 40.

The use, operation and advantages of my invention vwill be readilyunderstood upon reference to -the diawings. lt will be seen that whenthe receptacle 13 is in its normal position, that is, in a horizontalplane, the material to be mixed may be introduced into the same throughits inlet end 20, and that when the handle'46 is rotated, saidreceptacle will, through the gears 41, 43 upon the shaft 40, be rotatedto thoroughly mix The outer end of the shaft 40, 4

its contents. When it is desired to discharge said contents, the dog 35is disengaged from the lever 30 and thelong arm of the latteriselevated, to permit the swinging frame 12 to tilt to the position shownin dotted lines in Fig. 6v oi the drawings. In'this position, thereceptacle 13 will b'e inclined downwardly with its discharge end 21lowermost, so 'that the contents oi said receptacle may pass out oi thesame.

While I have shown and'described the preferred embodiment of myinvention, it will be -understood that I do not wish to be limited tothe precise construction herein set forth, since various changes in theform, proportion and the minor details of construction may he resortedto Without departing from the principle or sacrificing any of theadvantages of this invention.

Having thus described my invention, what l claim as new and desire tosecure by Letters-Patent is:

1. In a mixing machine, the combination of a main frame, a tilting framepivotally mounted therein on one side of the center of weight thereof, areceptacle carried tilting frame on the weightier end thereof, and meanscon? nected to the main frame to lock said lever in an adjustedposition.

2. A mixing machine comprising a frame having journal hearings and anintermediate supporting fric-tion roller, a tilting frame havingtrunnions to turn in said bearings and a curved rib to engage saidsupporting roller, a transversely disposed hollow mixing receptaclemounted to rotate in said tilting frame and having inlet and outletopenings at its opposite ends and'angularly disposed internal agitatingwings, a gear wheel upon said receptacle, a shaftyin said tilting frame,a pinion upon said shaft, in mesh with said gear, means for rotatingsaid shaft, and means for supportingthe overhalanced portion of saidtilting frame, substantially 'as described and for the purpose setforth.

In testimony whereof I have hereunto set my hand in presence of'twosubscribing witnesses. l
